Walkman: A História Ilustrada (1979–2004) A timeline of Sony’s cassette Walkman models from 1979 to 2004 - EP.13 - 1985: SONY WALKMAN WM-101

 

Also released in 1985, the WM-101 used a slim rechargeable “gum stick” cell while retaining AA

 support. Weighing under 200 grams, it favored portability. It shipped in black, red, light blue, and

 gray.

Unveiled in 1985, the WM-50 moved away from sharp-edged housings in favor of softer

 contours. The change improved handling and comfort, signaling a turn toward ergonomics over

 rigid form.

1985 WM-F75: The Radio-Equipped Sports Walkman.

The WM-F75 added a full AM/FM radio to the WM-75 platform, and you can see the changes in the body. A rear bulge housed the AM ferrite antenna, and the internals were rearranged to make room for the tuner. The tuning scale ran along the edge of the cassette door, linked to a rear tuning wheel, and the indicators expanded beyond basic battery status. To keep the radio controls sealed, Sony dropped the second headphone jack.

1985 WM-75: The Compact Sports Walkman

The WM-75 refined the original Sports Walkman idea into a more compact, everyday package. It kept a serious mechanism and feature set, with Dolby B, metal tape support, switchable auto-reverse, and dual headphone outputs. Sealing dictated the layout, pushing the battery and secondary switches inside the cassette bay. Even the porthole window was functional, with a raised rim and studs that protected the face when set down.
